\ IMPROVEMENT IN HAND-CULTIVATORS. Y.

Specication forming part of Letters Patent No. 176,845, dated May 2.,1876; application filed 1 December 20, 1875.

To all whom it may concern:

Beit known that I, JAMES K. DUGDALE, of White Water, in the county ofWayne and State of Indiana, have invented a new and useful ImprovedHand-Cultivator, the

nature of which consists in the employment of removable sliding framesfurnished with any approved style of cultivator-teeth, hoes, or rakes,for working the soil, made adjustable, so that they can be raised orlowered to suit the height of the operator, and attached to a framesupported by wheels; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being hadto'the accompanying drawings, forming a part of this specification, in

' Which- Figure l is a side elevation of my improved hand-cultiyator.Most of the parts represented are duplicated on the opposite side. Figs.2, 3, and 4 are enlarged views of parts hereafter described.

d d, in which the side pieces a a are inserted.

The whole is supported by a wheel, D; or there may be two wheels used.The wheel is placed between the tools and handlev at d'. This allows thetools to be raised or lowered, tosuit the irregularities in the soil, byraising or lowering the handle while .pushing the machine along.

'The side pieces a. a are curved upward from the wheel to frame B, whichallows of a smaller 4wheel and shorter side pieces being used than canbe when theyare made straight. The handle ends are slightly curved Othercross-.pieces or braces may be added, if needed for strength.

C is an adjustable and removable frame similar in shape to frame B, andmay be duplicated and provided with any number of vertical bars desired,and with teeth of any approved style for cultivating the soil, which lteeth are attached to the lower ends of the bars by any known method,either permanently or removable, and in a position best suited for thekind of work on hand. A separate frame may be used for each kind ofteeth; or one set of teeth may be removed from the frame and replaced byothers.

A frame with teeth attached is shown by Fig. 3, in which e e e are thevertical bars, and f f f the cultivator-teeth.

E is a right-angle sliding arm provided with a vertical bar, e', towhich a tool isattached. This arm slides under caps i i on frame G, andis held in place by a thumb-screw or spring. I

This device is intended io reach over the row, so as to cultivate onboth sides of the plants at the same time. y

Frame C is held in place against frame B by guides c', attached tostandards c of Y frame B. A sufcient number of these guides A.

are made to lap over in front, so as to hold frame C irmly in position.F is a device composed of a pin, button, and handle. The pin passesthrough an orifice in one of the bars of frame B, and through notches inone of the bars of frame G, and is turned over in front, forming thebutton, which Abutton laps over said bar and locks the frames B and Ctogether. by a handle or rod, h, which rod is held in place by a catchin rear ot' frame B. The button, being turned out from the frame, allowsthe notch to slip oft" the pin, when the frame may be adjusted eitherhigher or lower, or taken out and another frame put in, as desired. Thisdevice is shown by letter F, Fig. 2, and also by Fig. 4, in which gisthe pin; h, the handle, which handle may be a spring-rod; and j, thebutton.

The notches in frame C are designated by the letter k. There may also benotches in the opposite bar to catch on -a stationary pin.

This cultivator is operated by pushing it along, or by reversing theposition of the teeth by changing the same and pulling it.

Having thus fully described the construction and operation of myimproved hand-cul tivator, what I claim isl. The curved side piecesextended beyond This button is turned back and forth lthe Wheel, incombination with arched framey 4. The device F, serving bothas a. pinand button, in combination with frame C, having notches k, as and forthe purpose described.
